Structural materials for radiant coils at high-temperature plants in petrochemical complexes

On the basis of research results, rational alloying, and structural stabilization, the Central Research Institute for Structural Materials developed three types of heat-resistant and heatproof alloys with superior operating characteristics for use in various components of radiant coils — the low-temperature part and the high-temperature part of the tubing system, and the mounting and suspension hardware. Since the tubing system in radiant coils is a welded structure, welding materials (wire and electrodes) were also developed for installation and repair of such coils. The alloys developed have different levels of alloying elements, thereby enabling the alloys to be selected for use based on operating conditions. This rational approach to use of the new materials reduces the funds required for fabrication and repair of radiant coils.
